Oracle 选择具有间隔的连续值

我被以下代码困住了：

REM AWR-Generator.sql: Script for creating multiple consecutive Oracle AWR Reports
REM
REM Creates an output SQL script which, when run, will generate all AWR Reports
REM between the specificed start and end snapshot IDs, for all instances

这段代码生成一个spool文件，在开始捕捉和结束捕捉之间具有连续的捕捉ID。我想修改它，以便它要求一个间隔值，并用该间隔计算开始捕捉和结束捕捉

例如。 如果我将start_snap设置为1400，将end_snap设置为1404，间隔为2，那么它应该将报告设置为1400到1402，1403到1404

问候,，

您好，欢迎来到StackOverflow。不幸的是，对于这个有趣的问题来说，这可能是太多的代码和太宽的范围，不适合。如果您能够用代码清楚地隔离一个问题，并提供一个演示您的问题的示例，那么我们肯定会更好。@SylvainLeroux使用PL/SQL API而不是SQL*Plus脚本可能会有一个比较简单的答案。例如，.CURSOR c_snapshots是选择inst_num，start_snap_id，end_snap_id，从选择s.instance_number作为inst_num，s.snap_id作为start_snap_id，leads.snap_id，1，在分区上按s.instance\u number排序按s.snap\u id作为dba\u hist\u快照s中的end\u snap\u id为null，其中s.dbid=c\u dbid和s.snap\u id>=c\u start\u snap\u id和s.snap\u id@Jon Heller这段代码已经使用了DBMS\u工作负载\u存储库
